Dundee midfielder Mo Sylla is set to rejoin the squad following his suspension, while the fitness of defender Jordan McGhee and midfielder Scott Fraser remains under assessment.

Centre-back Joe Shaughnessy is steadily advancing in his recovery from a significant knee injury.

Meanwhile, Croatian centre-back Bozo Mikulic, who recently departed Partizan Tirana, is awaiting a work permit to finalise his transfer to St Johnstone.
